Hi!

After trying to take photos of 'perseid showers' i got a lot problems with dew gathering on my camera lens. It is extremally easy to fight with it using my new DIY weapon. Lens warmer! Extremally useful while shooting at night, especially long exposure nightscapes.

Things You will need:

- rubber material
- zip
- cutting device
- 2 ohm 5 watt resistors (12 pieces)
- power plug
- power cable
- short wires
- silicon glue

The device connected to the 12V car installation will give 6Watts of energy to Your lens.

You can also use other power supply to the device, the higher voltage, the more power it will produce. I think it is good idea to install extra switch to control the warmth of Your lens depending teperature of the air...


Take a look how to create lens-heater?:

(it should be available in few minutes after posting this thread)

If You have any question post them here. If You like it put apropriate rating to my video.

Cheers,
Robert

Brilliant. I will be taking more shots in the evening and will have shorter days here so this will be ideal.

Thanks

I've heard of people strapping hand warmers to their lenses but this seems much nicer.

Last night there was about 15Celsiuss degrees, and as always a bit wet outside (the dew gathered on my cars windows for example), the device was working like a charm (I put a cloth between the warmer and the lens, and outside the warmer).

Also it is nice to hear that some of You liked the idea.

Instead of the resistors, you may use resistive wire, similar to what is used in toasters, solder irons etc. A common producer of resistive wire is Kanthal, and most common is 2 to 20 ohm/meter, depending on the diameter of the wire.
